PAPER-CLIP- Specification of Letters Patent.

Application filed January 16, 1909. Serial No. 432,763.

To all whom it may concern:

Be it known that 1, DAVID G. GALBRAITH,

a citizen of the United States, residing at Mineral Wells, county ofPalo Pinto,-Texas, have invented a certain new and useful improvement inPaper-Clips; and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification and to theletters of reference marked thereon. This invention relates to devicesfor securing loose sheets of paper, etc., together, the objects of theinvention being to provide a simple device which may be cheaply andexpeditiously manufactured, and which will be easy to apply and willgrip the papers at two separated points in order to prevent the rotationor sliding of the sheets with the clip as a center.

A further object of the invention is to provide a device which will not'project an appreciable distance beyond the edges of the papers. 1

In the accompanying drawings,Figures 1, 2, 3, and 4 are views showinVarious shapes of formed blanks adapted for use in making clipsembodying the'present invention; Figs. 5, 6, 7, and 8 are'views ofcompleted clips made from blanks shown in Figs. 1, 2, 3 and 4,respectively.

he clip of the present invention is preferably formed of spring wire andmay be round, oval, e g-shape, or angular contour, as shown in Figs. 5,6, 7, and 8, respectively, of the drawings. In every instance the wire Aofwhich the clip is made is bent into a closed loop with the'endsoverlapping for a considerable distance. In the preferred con-.

struction theoverlap is from to a half the circumference of the loop andthe over.- lappin portions a, a v are equal distances from t e axis ofthe 100 but contact with each other only at the en s as indicated at Bwhere the extremities of each overlapping portion bearsagainst the bodyof the loop with considerable pressure. The intermediate parts of theoverlapping portions are spread apart and as they are curved around theaxis of the. loop project forwardly beyond the contact points therebyforming an open mouth G into which the edges of the papers may beconveniently slipped or into which said edges may be guided by thefinger and thumb between which the clip is grasped when being applied tothe papers.

When the clip is applied to the papers to be held the gripping points Bare separated a considerable distance from each other and are somedistance from the edges of the papers. The extreme ends of the wire bitePatented May 16, 1916.

into the papers and present no projections 1 beneath which other paperscan catch.

As a convenience in the formation of the clip it is preferably bent upin the form of a spiral as shown in Figs.-1, 2, 3, and 4 with theoverlapping portions substantially parallel throughout, and to completethe clip it is only necessary to spring one overlapping portion past theother to the position shown in Figs. 5, 6,7, and 8, the natural bend informing the spiral serving to form the open mouth C.

In the commercial formation of the clip as now practiced the spiral hasthe overthe mouth is formed by simply reversing the relativepositions ofthe overlapping ends with the result that the extremes only of theoverlapping portions will contact to form the gripplng points and theintermediate portions of the overlap will spread apart to form theentrance mouth for the edges of the papers.

Having thus described my invention, what I I claim as new and desire tosecure by Letters Patent of the United States, is

1. A clip for loose sheets, etc., made in the form of a uniform spiralloop with its ends overlapped not to exceed approximately one-half thecircumference of theloop, the overlapped portions contacting only attheir ends and the intermediate parts of the Over? lapped portions beingat all points correspondingly bent outwardly from \the' contactingpoints and spread apart between the contacting points parallel withthe'axis of the loop to form an entrance mouth for the edges of-thesheets.

2. A clip for loose sheets, et c., made subportions of the overlappedends will spread stantially 1n the form of a spiral loop with apart toform an entrance mouth for the its ends overla ped not to exceesubstanedges of the papers.
